  Changed paths:
    M op.c

  Log Message:
  -----------
  op.c - deal with not-reached statement warning

Change this to test on o, and if it goes null to panic.

We used to assume that o was a valid pointer and loop infinitely,
but this meant that the old return statement at the bottom of
function was never reached.

  Changed paths:
    M regcomp.c

  Log Message:
  -----------
  regcomp.c - simplify logic to eliminate unreached code

We always goto out of this if, so eliminate the unreached code
and also eliminate the useless else block.

  Changed paths:
    M regexec.c

  Log Message:
  -----------
  regexec.c - mark the bottom of a sub as never reached

We used to have a return statement here that picky compilers
would complain about.

  Changed paths:
    M sv.c

  Log Message:
  -----------
  sv.c - don't cast SVTYPEMASK to svtype.

svtype is an enum with 18 values. SVTYPEMASK is 31. A picky
compiler will complain that casting 31 to a svtype is an error.

Casting both sides to a U8 should silence this.
